5 weeks post liver transplant, can't eat at all! Help!

Hi all, I had a liver transplant October 25th. Acute failure from supplement toxicity! I was in the hospital for 5.5 weeks. Been out and in housing near the hospital currently. I am having HORRIBLE nausea and everything tastes like paste or worse. I seem to have a coating on my tongue or something. I am malnourished and struggling to eat. The thought of it makes me want to vomit. Any of you have this problem? How did you overcome it. Any tricks? I have a feeling it may be the Tacrolimus. We switched me to Tacrolimus LCP, but I still feel the same. I could be any of the meds really. I just need to eat!
